Here are the traces for one of the cores:

It looks like something wrong happened here:

  std::locale::locale (this=0x100783d0 <boost::filesystem::path::codecvt()::posix_lazy_initialization>, __other=...)
              at ../../../../../src/libstdc++-v3/src/c++98/locale.cc:80

in the libstdc++ library, since correct address was changed to 0x0 address in __atomic_add_dispatch .

BOOST :
libs/filesystem/src/path.cpp
  std::locale path::imbue(const std::locale& loc)
  {
    std::locale temp(path_locale);
    path_locale = loc;
    codecvt_facet_ptr =
      &std::use_facet<std::codecvt<wchar_t, char, std::mbstate_t> >(path_locale);
    return temp;
  }

/usr/include/c++/4.8/ext/atomicity.h

  static inline void
  __attribute__ ((__unused__))
  __atomic_add_dispatch(_Atomic_word* __mem, int __val)
  {
#ifdef __GTHREADS
    if (__gthread_active_p())
      __atomic_add(__mem, __val);
    else
      __atomic_add_single(__mem, __val);
#else
    __atomic_add_single(__mem, __val);
#endif
  }

It looks like some C++ object initialization went bad, for std::locale::locale .
